73. You will see the difference between precept and counsel, if you remember the case of him in the Gospel, to whom it is first commanded to do no murder, not to commit adultery, not to bear false witness; for that is a commandment which has a penalty for its transgression. But when he said that he had fulfilled all the commandments of the Law, there is given to him a counsel that he should sell all that he had and follow the Lord, S. Matt. xix. 18–21. for these things are not imposed as commands, but are offered as counsels. For there are two ways of commanding things, one by way of precept, the other by way of counsel. And so the Lord in one way says: “Thou shalt not kill,” where He gives a commandment; in the other He says: “If thou wilt be perfect, sell all that thou hast.” He is, then, not bound by a commandment to whom the choice is left.
